Um, as much as I'm in favour of not showing up your opponent and leagues having policies like running the clock(in hockey games) when there's a big goal differential, this strikes me as kinda heavyhanded.

I think they tried to enforce it a couple of times, but it didn't work. On one such occassion, a junior varsity kid broke off a 85-yard run or something like that at the end of the game.
The coach was like, "what am I supposed to do? Yell at him to fall on the 1?"
